PHP+js+html+mysql中互相傳值程序

本文章介紹了關於PHP & HTML & JavaScript & MySQL 代碼如何互相傳值 ，有需要學習的朋友可參考一下

1.PHP

a.PHP -> HTML & JavaScript

額 超簡單，我也要寫= =～

html代碼中

 代碼如下 復制代碼 <input type=""  readonly="readonly" style='background-color:#DCDCDC' value=<?php echo $perinfo[ID];?> />

　　 JavaScript代碼中

 代碼如下 復制代碼 <script type="text/javascript">
var ability=<?php echo JSON($array);?>;
</script>　

　b.PHP  <-> MySQL

php代碼中

 代碼如下 復制代碼

<?php
$dbcnx = @mysql_connect ( "localhost", "root", "1234" );
if (! $dbcnx) {
    echo ("Unable to connect to the " . "database server at this time.");
    exit ();
}

if (! @mysql_select_db ( "pms" )) {
    echo ("Unable to locate the joke " . "database at this time.");
    exit ();
}
mysql_query ( "SET NAMES 'GB2312'" );

    $q=mysql_query("select * from ability where ALV = 1");
    while($row=mysql_fetch_array($q)){
    $array1[] = $row[AName];
}
?>

2.HTML

a. HTML -> PHP (POST方式）

html代碼中

 代碼如下 復制代碼 <form id="form" name="form" method="POST" action="do.php">
<input type="hidden" id="count" name="count" value="1"/>
<input type="submit" name="Submit" value="Search"/>
</form>　

　do.php 文件代碼中

 代碼如下 復制代碼 <?php
echo $_POST['count'];
?>　

　b. HTML -> JavaScript

JavaScript代碼中 (可獲得，可更改）

 代碼如下 復制代碼

<script type="text/javascript">
var te = document.getElementById("count"); 
te.value = 1; 
</script>

3.JavaScript

a. JavaScript -> HTML (通用法, 未驗證)

JavaScript代碼中

 

 代碼如下 復制代碼 <script type="text/javascript">
function f(){
var id = "2";
var a = document.getElementById("a");
a.href.replace("(n)", id);
}
</script>　

　html代碼

 代碼如下 復制代碼 <a id="a" href="ExportArticle.action?articles=(n)"/>　　b. JavaScript ->

PHP

通過html的轉接

1.JavaScript代碼先給html

 代碼如下 復制代碼

<script type="text/javascript">
var i = 1;
var te = document.getElementById("count"); 
te.value = i; 
</script>　　2.html代碼給php

<form id="form" name="form" method="POST" action="do.php">
<input type="hidden" id="count" name="count" value="1"/>
<input type="submit" name="Submit" value="Search"/>
</form>　　3.do.php接收到

<?php
echo $_POST['count'];
?>
